Most of us are taught that the worst "World Wars" happened in the 20th century. World War I followed by World War 2 killed 70 million people and destroyed millions of square miles of land, property, and cities. 3 percent of the human populations died. My last book "World War Zero" described the World War before that [about 55 hundred years ago]. Worse than the more well known ones, 1/3 of the population of the entire world died and the world was sent back to a Stone Age existence, but that was not the worst World War. This book is about the World War before World War Zero. In this world war [ending 10 thousand years ago] almost every living person, animal, and plant died either during the war or by the ramification of the war. The planet Venus was destroyed, thousands of meteors hit the earth and the Earth shifted on its axis during the end of the war.We know it as the end of the Pleistocene Age
